Saluton TAG!

I'm requesting a TAG review of Pointer Events Azimuth Angle and Altitude Angle.

Currently Pointer Events captures pen inclination by using tiltX (tiltX) and tiltY (tiltY) angles - angles measured from two axes. This proposal is to add altitude and azimuth angles to Pointer Events and to allow user agents to transform from one set of digital pen inclination coordinates to the other automatically thus making both pairs of angles available to developers at the same time.
